Abstract
The relative strain energies of five types of ordered structures derived from a parent zinc-blende alloy A1−xBxC have been investigated. The most stable x = 1/2 and x = 1/4 or 3/4 structures are chalcopyrite and famatinite. Also investigated is the influence of order and strain on the bandstructure of the ordered compounds. Calculated tight-binding band gaps of ordered compounds of the All−xGaxAs family yield results not too different from those for the alloy. Band gaps for a same-cation family of compounds derived from GaAs1−xSbx exhibit a large bowing as a function of composition x similar to that reported experimentally for a metastable form of the alloy.

When experimental results are unavailable, we use theoretical estimates for the valence-band offset, as described in W. A. Harrison, Phys. Rev. BU, 5835 (1981) and in E. A. Kraut, J. Vac. Sci. Technol. B2, 488 (1984).

Others have also estimated the (001) superlattice band gap. For example, D. M. Wood, S.-H. Wei, and A. Zunger, Phys. Rev. B37, 1342 (1988) report a value of 2.14 eV, 0.10 eV below that for the alloy. The reported resonant Raman (0 0 1) superlattice band gap is 2.15 eV: M. Cardona, T. Suemoto, N. E. Christensen, T. Isu, and K. Ploog, Phys. Rev. B36, 5906 (1987).
For All,GaXAs, we use the experimental offset 0.48 eV from D. J. Wolford, T. F. Kuech, J. A. Bradley, M. A. Grell, D. Ninno, and M. Jaros, J. Vac. Sci. Technol. B4, 1043 (1986).
